6S Bulldozer For LGP Machines
Remove the center AccuGrade mast mount (A) or (B). Clean up the area as needed after part removal.
Use blocks to adjust the blade orientation in order to level the two end mounting plates (C) in both the side to side and fore/aft directions. Precise leveling of the two plates simultaneously may not be possible, however, minimize the out of level of both plates simultaneously. See Illustration 1 if 6SU blade or Illustration 2 if 6S blade.
Illustration 3 g03778536
(G) 141 mm (5.55 inch) (W1) 6 mm (0.24 inch) fillet with 1.5 mm (0.06 inch) of penetration on both sides, two times
Illustration 4 g03778638
(H) 85 mm (3.35 inch)
For 6SU blades only, position the center line of the 380-2439 Bracket As (1) midway between the deflectors (D) and 85 mm (3.35 inch) from the back of the blade. See Illustrations 3 and 4.

(J) 141 mm (5.55 inch) (W1) 6 mm (0.24 inch) fillet with 1.5 mm (0.06 inch) of penetration on both sides, two times
Illustration 6 g03778660
(W1) 6 mm (0.24 inch) fillet with 1.5 mm (0.06 inch) of penetration
For 6S blades only, position the center line of the 380-2442 Bracket As (2) midway between the deflectors (E) and against the back of the spill plate (F). See Illustrations 5 and 6.
Remove paint from areas to be welded. See Illustrations 3, 4, 5 and 6.
Adjust the orientation of bracket assembly (1) or (2) so that the AccuGrade mast mounting surface on the top of the bracket assembly is level in both the fore/aft and side to side directions and tack in this position.
Check that end mounting plates (C) and bracket assembly (1) or (2) are simultaneously level. Repeat steps 2 and 6 as necessary to make the new center mounting bracket parallel with the two end mounting plates (C) .
Weld bracket assembly (1) or (2) to the blade with welds (W1) on both sides of the two bracket side plates, as shown in Illustrations 3, 4, 5 and 6.Note: Taper welds at ends to agree with plate profile.
Paint welds and all bare metal in the area of work.
After the blade is mounted on the tractor, perform the AccuGrade "measure up" process with the AccuGrade receiver mounted on the new center mounting bracket.
